He was last seen at Clowes Memorial Hall, on the campus of Butler University, at around 7 p.m., Thursday, according to police.

“I’m trying so hard to keep hope high but as more time goes by its tough,” said Stephen’s father Erick Colbert, who plans to join his wife in Indianapolis Saturday.

Stephen is described as a black male, 5-foot-8-inches tall and 120 pounds. He was wearing a black jacket, orange shirt, and brown khaki pants. He is visiting Indianapolis with the organization Music for All.

Wylie sent their top administrators to join the search that they are optimistic will end well.

“We’re hoping he just got on the wrong bus maybe ended up at the wrong hotel and he’s scared to come back because he thinks he’ll be in trouble,” said Ian Halperin with Wylie ISD.

Wylie ISD realeased the following statement:

The Wylie ISD has been in contact with Stephen’s parents and at this time they have asked for prayers for his safe return. In addition, information about Stephen has been posted on Wylie High School’s Facebook page. The event sponsors, Butler University Police and the Indianapolis Metro Police Department have assured us that they are working hard to ensure Stephen’s safe return.

Our thoughts and prayers are for the safe return of Stephen.
